3 Claims. (01. 4-2177- This invention relates to improvements for water closets and more particularly to a toilet seat that is ventilated to remove obnoxious fumes or odors "from a toilet bowl while in use; and the invention consists of certain novel improvements in the details of construction and combination of the component parts thereof.

' The inventiontogether with its objects and advantages will be best understood from a study of the following description taken inconnection with the accompanying drawings wherein?- gure 1 is a side elevational view of a water closet illustrating'the application of the invention. 1

Figure 2 is a bottom plan view of the toilet seat..

Figure 3 is a detail sectional view taken substantially on the line 3- -3 of Figure 2.

' Figure 4 is'a sectional view takensubstantially on the line 4-4 of Figure 5.

Figure 5 is a sectional view taken substantially on'the line 5-5 of Figure 1.

Figure 6 is a plan view illustrating certain details hereinafter more fully referred to, and

Figure '7 is a detail sectional view through a ball joint and] taken' substantially on the line 1-1 of Figure '6. v

Referring to the drawings by reference numerals it will .be'seen that 5 indicates generally a conventional toilet bowl; 6, the fiush tank; I the pipe connecting the tank 6 with the bowl 5 and 8 a hollow walllstructure.

In accordance with the present invention there is provided for the bowl 5 a seat Q'and a lid or seat cover In.

The seat Sand lid In are hingedly connected together and hingedly mounted at the rear of the toilet bowl 5 through the medium of a pair of conventional hinges II.

In accordance with the present invention the toilet seat 9 which may be constructed of any suitable material is hollow as best shown in Figure 3 and has a fiat under side l2 adapted to rest substantially. and for a portion of its width on the upper edge of the bowl 5.

Atthe under side thereof and adjacent the outer edge of saidtoilet seat, the latter is provided as clearly shown in Figures 1, 2 and 3 with a depending flange side of the. bowl 5 at the top of the latter, the flange l3 extending across the front and along opposite sides of thebowl 5 for a considerable distance as will be clear from a study of Figure 1.

Suitably secured to the under face of the bottom l2 of the toilet seat 9 is a substantially U- H to either raised' or lowered of thetoilet bowl 5 so that the perforated area inwardly of the wall'of i3 that overlies the outer shaped strip M of rubber or other suitable material which'acts' as a sealing gasket between the seat 9 and the top edge of the bowl 5. Thus it will be seen that with the seat 9 in lowered position or in a position of rest on the bowl 5 5 substantially a sealed joint is provided between the bowl and its seat.

For the remaining portion of its width the bottom l2 of the seat 9 isprovided with slots or air holes l5 and extending from the back of the seat 10 9 is a conduit pipe section I6. The conduit pipe section lfiis connected through the medium of a union I8 with a pipe section l9 that is provided with a pair of integral branches that straddle the water feed pipe 'I. 16

A pipe section '2! is provided with a pair of branches 22 complemental to the pipe branches 20 and branches 22 are connected with branches 20 through 'the medium of unions 23 disposed at opposite sides of the pipe I. 20

Connected with the pipe section 2| as at 24 is a relatively short pipe section 25 one end of which is formed into a substantial spherical or ball 26 that has a working fit within a-socket 21 provided on one end of an intake pipe 28. 25

Pipe 28 extends through the wall 8 and is connected at one end as at 29 to the intake side of a casing 30-.

Leading upwardly through the wall 8 and con-- nected with the outlet side of the casing 30 is an 30 exhaust or discharge pipe 5|.

Casing 30 is concealed within the wall 8 as shown in Figure 1 and arranged within the cas ing is a fan 32 driven from an electric motor or other suitable source of power 33 also arranged.35 within the casing 30 as-clearly shown in Figure 4.

It will be. seen that by providing the ball joint connection 26, 21v between the pipe sections 25 and 28 seat 9 will be free to. swing on the hinges position, optionally.

In connection with the above it will be notedthat the under side l2 of the toilet. seat is of materially greater width than the top edge or rim l5 l2 of the seat will extend the toilet bowl so as to be in direct communication with the bowl.

From the foregoing it will be apparent that with the fan 32 in operation the foul odors will be drawn into the hollow of the toilet seat and from the toilet seat through the fan casing 50 to pass into-the atmosphere through the exhaust pipe 3|.

A suitable control switch, as at 34, may be of the bottom plate provided for controlling the flow of current to the construction, utility and advantages of an invention of this character will be had without a more detailed description.

Having thus described the invention what. is

- claimed as new is:

'1. The combination with a closet bowl, of a,

.hollow seat member on said bowl, said seat memher having 9. depending flange extending downwardly into overlying relation with the bowl at the upper edge of the latter,- said' seat being also provided on the under side thereof 'with perforations establishing a ventilating connection between said bowl and said seat and a ventilating pipe communicating with said seat, and a gasket member secured to the under side of said seat within the confines of said flange and arranged to i contact the upper edge of the toilet bowl when the seat is in a position ofrest on said toilet bowl, a casing interposed in said ventilating pipe,

, and a power driven fan for drawing air through 'the ventilating pipe housed within said casing.

and said ventilating pipe including a section communicating with said casing, a second section communicating directly with the toilet seat, and a hollow ball and socket joint connection between the said sections of the ventilating pipewhereby said seat is free to swing vertically relative to the toilet bowl.

2. The combination with acloset bowl, of a hollow seat member on said bowl, said seat member having the under side thereof of materially greater width than the width of the wall of the closet bowl at the upper edge of the latter whereby a major portion of the underside of said seat member extends inwardly from the wall of the toilet bowl, said seat having said major portion of the width of the underside thereof provided with perforations establishing a ventilating connection between the bowl and seat, said seat adjacent the outer peripheral edge thereof being provided with a depending flange extending downwardly into overlying relation with the bowl at the outer side of the latter, and a gasket secured to the imperforate under side of said seat within the confines of said flange to contact the upper edge of the toilet when the seat is in a position of rest on said toilet bowl.

3. The combination with a closet bowl, -of a hollow seat member on said bowl and provided on the underside thereof with perforations establishing a ventilating connection between said bowl and seat, a fan casing, a power-driven fan in said casing, a ventilating pipe including a section communicating with said casing and a second section communicating directly with the toilet seat, and a hollow ball and socket joint connection between the said sections of the ventilating pipe whereby said seat is free to swing vertically relative to the toilet bowl. v 1
